Function axum_debug::check_service

pub fn check_service<S, ReqBody, ResBody>(_service: &S) where
    S: Service<Request<ReqBody>, Response = Response<ResBody>> + Clone + Send + Sync + 'static,
    S::Error: Into<Box<dyn Error + Send + Sync>> + Send,
    S::Future: Send,
    ReqBody: Send + 'static,
    ResBody: Body<Data = Bytes> + Send + Sync + 'static,
    ResBody::Error: Into<Box<dyn Error + Send + Sync>>, 

Checks if provided service can be used with Router.

This function is useful when debugging a Service.

Example

use axum::{handler::get, Router};
use axum_debug::{debug_handler, debug_router, check_service};
use tower::util::BoxService;

#[tokio::main]
async fn main() {
    let service = BoxService::new(get(handler));

    check_service(&service);

    let app = Router::new().route("/", service);

    debug_router!(app);

    axum::Server::bind(&"0.0.0.0:3000".parse().unwrap())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

#[debug_handler]
async fn handler() -> &'static str {
    "Hello, world!"
}
